...and it came up with nothing useful. i need to replace the cap and rotor on my '83 but when i was at the parts store there were two different options for the cap. no idea which one to buy, can someone help me out please? BTW its a 4-spd, 4wd....

Mark your spark plug wires and keep note of #1 plug on the cap.

 

Drive to parts house, take off the cap and wires (from the motor) and compare.

 

EA81's AND EA82's are sometimes hard to get parts for, e.g. parts guy gives you the wrong stuff

I think this is the difference from Hitachi and Nippon Denso Disty's?

yah those were the brands they told me. which one do i get?

they used different distys for 4 wd and 2 wd as well

I think someone who knows all the differences should post up a thread with pics for the USRM, I think this could help a lot of people

yah that's also throwing me off

92justy you are the man! as soon as i have time i'm pulling off my heat shield cuz according to that the hitachi cap doesn't have a rubber cap on the top and the design is different so just take just one look now thank you very much!

The 4WD uses the Hitachi pictured in the previous post. the rotor is kind of flat. The Nippon Denso one is the 2WD and the rotor electrode sticks out from the plastic part of the rotor. You could do an internet parts search for the distributor, rotor, and cap. Most parts suppliers will provide a little picture, and you can determine the proper parts before going to the parts store. Once you know what you need, call the nearest stores, see who has them in stock, and then you can go compare directly. I have had some trouble getting the right rotor myself, even after doing that. You have to be your own advocate, so know before you go, and you increase you chance of success. I have also found that the parts store person is a lot less dismissive if you demonstrate that you have done some research.
